Back when I wanted to play Castle of the Winds I experimented with visualization. The results weren't too impressive due to mouse lag. I ended up installing Windows 3.1 in DOSBox and playing all my games that way. Worked well enough.

I tested DOS in DOSBox extensively and found it's only useful to a tee.

I realized I already had a copy of VMWare Workstation. So I reinstalled, and made virtual drives for FreeDOS 1.1, MS-DOS 6.22, and MS-DOS 7.10. Will probably do Windows 98 and Ubuntu as well.
Am also considering emulating Raspian for Raspberry Pi development.

The reason for the various versions of DOS is that while FreeDOS is nice, I missed the old DOSSHELL program.
Furthermore, as I understand it, there are certain utilities included in MSDOS that FreeDOS just hasn't yet cloned perfectly, while FreeDOS has advantages of it's own. Therefore, some work is to be done in order to cobble together the best of both worlds, but it is not outside my means.

IMMA PLAY SOME WAR2 DOS YO!! WHO WANNA MEET UP ON DA KALI AND DWANGO!?1
